Heterocycles

Heterocycles are a type of compound that contains atoms of at least two different elements, where one or more of these elements are part of the ring.
Heterocycles can be incorporated with elements such as oxygen, nitrogen, sulfur, and others.

Classification of Heterocycles

Tetrahydrofurane and 1,4-dioxane are nonaromatic heterocycles.
Nonaromatic heterocycles belong to the class of aliphatic heterocycles.
Pyrrolidine and piperidine belong to the category of saturated heterocycles.

Properties of Heterocycles

Compounds with parallel chemistry to open acyclic relatives are referred to as heterocycles.
In pyridine, nitrogen replaces one of the CH groups in benzene.
The nomenclature prefix for a sulfur atom in a heterocyclic compound is 'thia'.
The IUPAC recommended naming system for three- to ten-membered heterocyclic compounds is Hantzsch-Widman nomenclature.

Characteristics of Heterocycles

The main property of oxiranes is that they are highly reactive due to ring strain.
The properties of three-membered heterocycles are described as highly reactive and strained due to ring strain.
In Hantzsch-Widman nomenclature, the prefix 'aza' is used to indicate the replacement of a CH group by a nitrogen atom.

Fused Aromatic Rings

Compounds that contain fused aromatic rings are referred to as polycyclic aromatic heterocycles.
